Hey there,

Been trying to test it with both Ryujinx and Yuzu and i haven't been able to get it working but i am not sure i have set it up properly.

Could you confirm that it works with either ?

Hey! This isn't exactly an issue with Super Mario Bros. 35

I was trying to adapt this custom server to the Splatoon 2 Global Testfire, and I managed to get the console to connect to my PC which is hosting the server, but then I realized that it was just giving me error 2306-0102, (only when I had the server up of course). And yes, I have indeed changed the access key to match that of the testfire. Also, I've placed an image of the error screen at the bottom of this post.

From what I can tell, there are a few needed funcs that aren't yet implemented... Is there any chance you could perhaps implement a few of them? I tried making some adjustments but I had no luck. I'm thinking its just a few authentication funcs. Maybe matchmaking eventually, but I'm not worried about that yet haha.
I'm assuming that I should probably also mention that handle_validate_and_request_ticket_with_custom_data is where it's failing.

If you need more info, lemme know!

Error Screen

So we've managed to get a few friends set up their Switch to connect to our own hosted private server, and we finally had around 3-5 players a lot of the time.

We were wondering why almost everyone except the final two players would always immediately get an Error 2306-0103 upon death.

So it seems spectating is broken, anyone who would end up in spectate mode instead gets that error.

One of them suggested it might be because of the game trying to submit coin rankings to the (non-existent) coin leaderboard. But I decided to check the logs and it was:
WARNING:nintendo.nex.matchmaking_eagle:MatchmakeRefereeServer.end_round_with_partial_report not implemented

Is there a quick way we can fix it so spectating works (if the issue is the coin leaderboard thing as they guessed)?
We plan to implement coin leaderboards eventually (even via something simple like SQLite), but for now, we hope to get spectating working at least since that's most of the fun of the game.

Also, when someone gets the error, the server just keeps spamming stacktraces (ClosedResourceError) in the log until the game ends (not sure if this is helpful):

Thanks for any help, and also thanks so much for writing the server code!
It's amazing!

We noticed in several games, some people would be frozen in place, never time out, and beat us all after we reach fastest red timer and time out.

At first we thought it was a hacker, until one of us got a connection error and also had the same result.

Now we can reproduce it reliably:
Steps to reproduce:

1. Have 2 or more players join a lobby, then wait until the game starts
2. One player presses the home button, closes the game by pressing X.
3. That player is now "immortal" in the game, will never run out of time, and cannot be beaten by the remaining players.

This is the error that appears once they close the game:

And of course, this initiates the ClosedResourceError stacktrace spam until the end of the game

In a scenario such as this where its server software under GPLv3 hosting a server does not qualify as "distributing" and therefore does not actually require source code to be made public.

It should instead be licensed under AGPLv3, which contains an affero clause, which also makes distribution of services over a network such as the internet qualify as "distributing".

In its current state it may as well be public domain with no protections on it due to its nature.

I was wondering if this method you used to use an alternative server instead of the nintendo server is possible to be used in other games like: splatoon, smash, mario kart ...

Is it possible that this open source server is made workable by only DNS modding? E.g. a DNS server that serves your server IP instead of the actual Arika/Nintendo one? I believe it will be possible and you should focus on this. I prefer to not mod my switch and it will be much more accessible for everyone if possible.

When connecting to my server, matchmaking works (players that join and leave show up properly, late joining players get the correct gamestart countdown time).

However, once countdown finishes, and game is about to start with "Here we go..." message, game doesn't start and instead clients get an "Error 2623-1011".

No visible errors are seen in the server logs (with either logging.INFO or logging.DEBUG levels).

My setup

• Brand new clean Ubuntu 20.04 VPS
  • nothing installed except python3 (Python 3.8.5 according to --version), pip-python3, git, and snap/certbot
  • Used git clone on https://github.com/kinnay/NintendoClients/
  • Ran "pip3 install ." in the cloned folder, successfully with seemingly no errors
  • Used git clone on https://github.com/kinnay/SMB35
  • Created "resources" folder inside the cloned folder, and copy-pasted all the generated *.pem files into it, which were generated as so:

• Then, I simply ran "python3 main.py"

Below are the consoles I used to connect:

• Console 1:

  • version 12.0.0|AMS M.19.3|E in settings
  • brand new clean Atmosphere install, added nothing except
    • exosphere.ini for emummc prodinfo blanking
    • my own IPS in atmosphere/exefs_patches/patch
    • 90DNS set up in the emuMMC

• Console 2:

  • version 11.0.1|AMS M.19.3|E
  • brand new clean Atmosphere install, added nothing except
    • exosphere.ini for emummc prodinfo blanking
    • my own IPS in atmosphere/exefs_patches/patch
    • 90DNS set up in the emuMMC

Also, Hekate's "Fix Arch Bit" is used afterwards every time files are copied over.

The IPS patch file I am using was created like so:

After they connected, during matchmaking, they show up properly on the dashboard:

Below is the logging.INFO log, from startup all the way up to Error 2623-1011

Here is the logging.DEBUG log (note at the end I close the software on both Switches):

• https://pastebin.com/raw/DdcHVif5

More Testing:

• I replaced the patch file with the stock one that redirects to "smb35.ymar.dev:20000", and the game works properly after matchmaking.
  • Nothing else was replaced/changed except the patch file.
• I replaced the patch file with one I created to connect to "bluephynix.de:20000", the person in the other issue. The game works properly after matchmaking.
• Replaced it back with my own patch file and I get "Error 2623-1011" when the game is about to switch from matchmaking to relay server mode.
  • Matchmaking works perfectly (leaving, rejoining, etc. shows up properly, as well as the reduced countdown timer), can also play Practice mode.

It must be something with my setup, but my setup is pretty barebones as it is

• nothing on the VPS but python3 and let's encrypt certificate from certbot (no webserver even)
• ports are confirmed open (matchmaking works, dashboard works)
• clean Atmosphere installs on Switches
• replacing the patch file with other servers works (ymar and bluephynix patch files work)

I've tried it on other VPS boxes I had access to (even tried it on an OSX box with Python 3.7), as well as some other certs available to me, and I get the same error. But it instantly works once I point it to those two known working servers.
EDIT: Just tried to update my VPS to Python 3.9 and run it there, still got the same error code.

I hope you can help me figure this out.

Hello, can you help me please to create an ips patch for my domain?

Hello kinnay,
i have a question to participants, is it possible to limit the max participants from ( 35 ) to ( 5 )for example ?
It is a good feature for nearly server test

Is there a way to play this without modding the switch? Or does it have to be modded?

Can he support other games? such as monster hunter rise

Please renew the Let's Encrypt certificate for https://smb35.ymar.dev:20002 as it expired on July 18th.

I have never modded any switch game.

Hi Kinnay

Is it possible to make it work on SXOS?
